"Nicky explains that Android is flexible and there are a few options for enterprises to host and publish their corporate applications on managed devices with managed Google Play. Which one of the following hosting and publishing methods are NOT supported by managed Google Play?"

Managed Google Play is designed to provide a secure and controlled environment for distributing applications to managed Android devices. Side-loading applications directly from a business website bypasses the Managed Google Play infrastructure entirely, offering no management, security, or version control benefits within that ecosystem. While technically possible on Android, it is not a method supported by Managed Google Play for app distribution. The other options are all valid methods within Managed Google Play: Self-hosted private apps on a business server can be linked and distributed through Managed Google Play. Publishing public applications is the standard Google Play Store functionality, which Managed Google Play leverages. Google-hosted private apps are a direct feature of Managed Google Play, allowing organizations to upload and distribute their private applications securely.
